How do I prepare my 3D file to print?

To print a 3D file on the Makerbot, you need to use their proprietary software, Makerbot Desktop. You can access this program on the iMac in the Makerspace, or you can download it on your computer: http://www.makerbot.com/desktop

If you don’t have a file to print already, you can find a whole database of 3D files on Thingiverse, Makerbot’s repository of free designs. Access Thingiverse from the “Explore” tab on Makerbot Desktop. Once you find a file you like, all you have to do is click the red “Prepare” button. It will then take you to the “Prepare” tab.

If you have your own file, first make sure it has a .stl or .obj file extension. You can then add it under the “Prepare” tab by clicking “Add File.”

Most files on Thingiverse are ready to print, but when you add your own file, you may have to make some adjustments in Makerbot Desktop to make it printable. This could involve rotating, scaling, or moving it on the build platform, which is all possible from the controls on the left of the application. It’s important that the build is directly on the platform.

Once the object looks good on screen, click the “Settings” tab at the top of the application. You want to make sure “Raft” is selected, giving your print a platform. This will prevent warping and make it easier to remove the print from the build plate.

If your print has any overhangs, then you’ll want to select “Supports.” Supports are necessary to make sure the overhangs will print successfully and not sag down. You do want to make sure that you orient your print in a manner to avoid as many overhangs as possible, as supports are somewhat difficult to remove and are often an unnecessary use of filament.
